Operation
During the normal operation, the refrigerator’s (or freezer’s) compressor would turn
on and off, in order to maintain the cold temperature in the storage chamber.
In this controller, the point where the compressor is cut off is called “SET POINT”.
The point where the compressor is turned on is calculated by adding the value of
“SET POINT” and “Hy” (temp differential).
For example, if you wish to maintain the operation temperature between 3°C and
7°C, you would set “SET” = 3°C, and “Hy” = 4°C.
“ALU” is the high temp alarm point, and “ALL” is the low temp alarm point. Both
alarm settings will alert users when the refrigerator’s (or freezer’s) temp is out of
range, via visual & audible alarm, and remote alarm contact.
“US” is the upper setting limit, and “LS” is the lower setting limit. Both limit settings
will prevent users accidentally adjust “SET”, “ALU”, or “ALL” outside the range.
